"Cough..." The teacher put his fist in front of his mouth, coughed and gave himself courage, avoided Gu Aotian's gaze, and said in a pretentious manner: "Since... Jenny said she wanted to take care of her, then we... let's have a simple question suitable for the undead - please try to shape the energy liquid into an icosahedral."

Silent.

When the students around him heard this, their faces were confused.

Previous tests were all about shaping energy liquid into spherical or rectangular objects, and cones were almost the most difficult problem.

What the hell is icosahedron? Even I can’t imagine it.

Just as they tried their best to imagine this ghost thing, Gu Aotian turned his head and looked at the teacher: "The surface of my icosahedral is still a little uneven, please give me some more time."

“…”

Everyone stared at the crystal ball in Gu Aotian's hand, where there was a round thing like a big black pineapple, or a black ball with triangles on the surface.

This...this...this is the legendary icosahedron?

If you don't look closely, you will think it is a rough sphere, but if you look closer, this thing really has many aspects.

Everyone has seen the icosahedral for the first time in their life.

That is an existence above imagination.

That is the ultimate bloom of the beauty of geometric laws.

It is like a work of art that has risen to a dimension.

Jenny's holy light shook again.

The examiner walked to the crystal ball tremblingly. He was actually not sure what the icosahedral looked like. All he could do at this time was counting: "1, 2, 3...16...20."

"It's really an icosahedral!" The examiner exclaimed with his head in his arms, "It's really an icosahedral!"

He then stared at Gu Aotian and said, "How did you... do it?"

"This is just a high school geometry problem, it's strange if you can't do it." Gu Aotian looked at the teacher's appearance, and his first reaction was that he felt that the teacher's level was not good, but he quickly felt relieved and cheerful.

It’s because you are wrong, just like only writing the answers and not writing the process when solving math problems, you won’t get any points. The teacher is kindly reminding yourself to write the process when solving the problem.

"I understand." Gu Aotian relaxed the energy manipulation and let the energy liquid return to its original appearance. "I will demonstrate it to you at the speed of 1/32 just now."

Gu Aotian began his performance.

"Thank you very much for asking such a simple question. It would be troublesome if it is a twenty-one-sided experience, but the twenty-one is the only positive solution, that is, the regular icosahedron. This means that I don't need to use any brains, nor do I involve calculus and advanced mathematics. I can do it with just junior high school mathematics. Thank you again for your care."

"So first, we determine the center of the icosahedron, undoubtedly in the middle of the crystal ball."

"Since it is an icosahedral, you will know with a little common sense that it has thirty edges and twenty sides."

"After a little calculation, these twenty faces must be twenty equilateral triangles, and all edge lengths are the same, so everything becomes extremely simple. First, I roughly measure the volume of the energy liquid, probably..."

"Then is a junior middle-level root equation. You can roughly calculate the edge length by oral calculation..."

"In this way, I determined all the parameters. Based on the edge length I calculated roughly, I will try to make an equilateral triangle face first."

"Then there is another surface, and the angle between this surface is 116.56505°, and the angle between all surfaces is 116.56505°. By the way, I'm lazy here. This angle is directly quoted based on memory, but it doesn't matter if I forget it. It's easy to calculate, just arccos(-1/√5). Although it's difficult to calculate the five decimal places after the decimal point, it's enough to get to 117°."

"Then the third face. Since the edge length and angle are determined, we only need to make an equilateral triangle mechanically and put it together with the two front faces."

"There is the fourth and fifth ones after that...you will find that the easier it gets to the back."

"Well, twenty." Gu Aotian fiddled with the Icosahedral in the crystal ball, "But what I did was not very good. I couldn't keep the surface of the Icosahedral absolutely flat and smooth. After all, the solution is fluid and it is difficult to manipulate."

The form in the examiner's hand fell on the ground like fallen leaves.

The students only felt that they had heard a stinky and long spell that destroyed the world and the earth level.

The examiner looked back at Jenny, and the expression was very clear - I'm so fucking, it's really hard to do it.

Jenny also covered her face and expressed her gratitude.

"I must give you the only full mark ever..." The teacher silently picked up the transcript, filled in the numbers, and handed it to Gu Aotian. Although the other party was a skeleton, his awe of magic was beyond species. Facing Gu Aotian, he was even a little humble: "Congratulations, you will be admitted directly, the full scholarship, and your understanding of energy manipulation has exceeded my personal understanding."

"Ah?" Gu Aotian said in shock, "Is one icosahedral enough? I know thousands of people who can do this, and this is only at the age of 14."

Jenny's heart sank after hearing this.

Is the academic culture of the Undead World... already so strong...

The examiner asked in a trembling voice: "Are you Gui Geng?"

"This..." Gu Aotian lowered his head and said shyly, "I went to school a little earlier than others, and I am almost 12 years old."

"...Is the age of the undead based on a hundred years?"

The cheers from not far away broke the astonishment here.

Gu Aotian looked in the sound, and the golden energy was rippling, and then it was all wrapped in one direction and was being sucked in by someone.

"Thank you, teacher, I'll go to the next test first." Gu Aotian threw down the stunned people and ran to the "inspiration" test site with his transcripts. This is the second test for the mage major.

Gu Lingyue stood on the stage, raised her hands high, and shouted: "It's all for me to get rid of - the anti-gravity force field!"

All the testing equipment on the stage flew up, from the table and chairs to the poor tilapia in the fish tank.

For a moment, demons danced around, and Gu Lingyue danced like a witch skeleton in a horror movie.

While the students were surprised, they received warm applause.

"Fuck is an anti-gravity force field!"

"The legendary seventh level spell."

What's even more terrifying is that some people are already crying.

"Mom, I've seen the seventh level spell!"

"This life is worth it!"

"Okay, enough is enough..." The examiner stood up nervously and said, "Student Gu, don't kill the fish, the students behind you still need to use it."
Chapter completed!
